FILTER FOR COFFEE-POTS.

EEPECIE'ICATION forming part of Letters Patent No. 307,969, datedNovember 11, 1884.

(No model.)

To all whom it may concern.-

Be it known that we, EDWARD B. MANNING, of Meridcn, county of New Haven,and State of Connecticut, and HENRY A. MANNING, of New York, in thecounty of New York and State of New York, have invented a newImprovement in Filters for Coffee-Pots; and we do hereby declare thefollowing, when taken in connection with accompanying drawings and theletters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of thisspecification, and represent, in

Figure 1, a sectional side view of a coffeepot with the filter in place;Fig. 2, a diagram illustrating the method of cutting the blanks to formthe bag; Figs. 3 and 4, perspective views showing the method ofstitching up the bag; Fig. 5, a diagram illustrating the modification ofthe cut; Fig. 6, a side view of the bag complete; Fig. 7, the dividedring detached.

This invention relates to a device for use in cofiee-pots to hold theground coffee in the upper part of the pot, so that water may be pouredthereon and run through into the pot below, commonly called filters, andpartic ularly to filters which are made from fabric and of bag-likecharacter, the object of the invention being to provide the pot with aninternal bottomless cup combined with a fabric bag at the bottom of thecup; and it consists in the construction of the bottomless cup and bag,as more fully hereinafter described, and particularly recited in theclaim, whereby the bag may be readily attached or detached from thebottomless cup.

Preferably we make the filtering-bag in one piece. \Ve cut the blank inT shape, as seen in Fig. 2, A, or the upright of the T, representing thebottom of the bag, and the cross that part which will form the body. Theupright is cut substantially square, and the projections B B, each side,in length correspond each to one of the sides, and little more than halfof the third side. The blank thus cut, the cross portion is turned up atright angles to the bottom A, as seen in Fig. 8. Then the projections Bare bent around the bottom, and the lower edge stitched to therespective sides of the bottom, the two ends of the cross broughttogether and stitched, as at a, Fig. 4, which completes the bag, andmakes practically a square bag.

Instead of making the cut in T- shape, it

may be L-shaped, as seen in Fig. 5, the longer side B turned up andcarried around the three sides of the bottom and joined at b, with thesame result.

The filter or bag is usually attached to a bottomless cup to be set intothe top of the pot. 0 represents this cup. Upon the outside of the cup,near the lower end, an annular groove, d, is formed. Into the upper edgeof the bag D a divided ring, E, is introduced. This may be done byinclosing the ring in the upper edge of the bag, as seen in Fig. 6. Thediameter of this ring (see Fig. 7) in its normal condition isless thanthe external diameter of the cup 0; but because of its being cut ityields so as to be passed on over the end of the cup until it arrives inthe grooved, where it automatically contracts and embraces the cup withsufficient force to hold the bag to the cup, but yet allow of itsremoval for cleansing or other purposes. By this construction we producea cheap and durable filter, and one which may be readily cleansed.

\Ve are aware that filters for coffee-pots have been made consisting ofa bottomless cup and a fabric bag attached thereto; and we are alsoaware that a divided ring, broadly considered, has been employed tosupport a cloth bag inside a coffee-pot; but we do not claim either ofthese features, broadly; neither do we make claim to the method ofcutting the bag, but simply show it as a convenient method of so doing.

Ve claim A filter for coffee-pots, consisting of the bottomless cup 0,constructed with an annular groove, d, upon its out-er surface near itslower end, combined with the fabric bag D, provided with the dividedelastic self-contracting metal wire ring E, introduced into its upperedge, and corresponding substantially to the groove (1 in the cup, andwhereby the upper edge of the bag inclosing the ring may be placed overthe lower end of the cup, and the divided ring contract to engage thegroove (Z in the cup, substantially as described.
